Sandal with adjustable straps and interchangeable mix and match straps and insoles

ABSTRACT

A sandal which includes two molded plates which releasably lock together. The underside of the male plate contains a male lock, and its front and rear underside contain the reciprocal fasteners to secure the straps. Ongoing styles of mix and match shoe straps overlap the front and rear sides of the male plate and their ends are secured on its underside with reciprocal releasable and non releasable fasteners. An example choice of hook and loop fastener provides a continuous releasable and adjustable benefit in vertical and horizontal directions for maximum comfort. An example of gluing the straps to the underside of the male plate will have the same custom comfort benefit only once, but will retain the ability to mix and match insoles, and straps and be interchangeable to a plurality of base styles. Multiple base styles (heel, flat, wedge) contain a hollowed out center area which creates a perimeter sidewall into which the female plate sized to fill the sidewall is inserted and permanently secured within. The superior aspect of the female plate contains the reciprocal “female” releasable locking mechanism for the male lock. After the straps are secured on the male plate it is inserted and releasably locked when the underside lock of the male plate enters the superior lock of the female plate embedded in a base style (heel, flat or wedge) When the male plate with straps is the top layer its underside is the lock and its superior side is the contact support for the foot. The male plate functions as a middle lock if an insole is inserted under the straps and its underside is removably secured to a superior aspect of a male plate with a choice of hook and loop fastener. The insole becomes the final layer which hides the shoes components and provides the contact support for the foot.

FIELD OF THE INVENTION

The present invention relates generally to footwear, and more specifically, to a sandal with adjustable and replaceable straps and replaceable insoles which are interchangeable to a variety of shoe bases to allow aesthetic and functional changes to the shoe

BACKGROUND OF THE INVENTION

Footwear comes in a vast variety of styles and designs to suit numerous functional and aesthetic goals. People are all individuals with variances in body parts, including their feet. Foot specifications vary in width, bone structure, toe lengths, protrusions, and varying positions of instep. One foot may be wider then the other. All feet are different and individuals are often uncomfortable in over the counter footwear. The present invention enables the consumer to adjust the straps in vertical & horizontal directions to increase their personal comfort. Custom molded shoes can be expensive and the present invention would offer this benefit for a moderate amount of money. The present invention also offers the consumer the ability to mix and match straps and insoles to a variety of base styles (heel, flat, or wedge) of the same size. Having each pair of straps mounted to its own plate makes it convenient to simply slide and lock into the base. It maintains the personal adjustment for next time. All of the possible variations increase the consumers ability to affordably increase their amount of foot attire.

BRIEF SUMMARY

A sandal comprised of layered footwear components containing a base of multiple styles (heel, flat, or wedge), all of which have a hollowed out center which creates a perimeter sidewall into which a molded female plate which completely fills the inside perimeter wall is inserted and permanently glued within to create one layer. Said bases and female plate may be molded as one piece if desired. The superior aspect of said female plate contains a receivable releasable locking mechanism for the next layer male molded plate. The male molded plate contains the reciprocal releasable locking mechanism for the female plate on its underside and a choice of hook and loop fastener (or other releasable fastening means) secured to the underside of the male plate. Straps which have reciprocal fastening means are attached to the underside of the male plate. Straps which are applied with non permanent fasteners are repeatedly adjustable and transferable to any male plate. Straps which are permanently applied to a male plate maintain its customized placement for comfort in vertical and horizontal directions for future use. All male plates with straps releasably combine with any style base. An additional padding may be permanently glued to the superior aspect of any male plate. An alternate design would be to releasably attach an insole to a male plate by inserting it under the straps and securing its underside to the superior aspect of the male plate with choice of hook and loop fastener (or another releasable fastener). The final layer insole or superior aspect of the male plate is the contact support for the foot which hides the shoes components and when assembled the sandal looks and functions like a usual and customary shoe design.

DESCRIPTION OF RELATED ART

Tsai and Yang both attach their straps to the shoe base. My design attaches the straps to a removable plate, and the adjusted straps are easily transferred on the plate to multiple base styles. There is much more flexibility and convenience for the consumer with my new design.

Neither invention allows for the straps to be adjusted both vertically and horizontally for maximum comfort.

My design is made from moldable parts and has minimal or no hardware. Straps snap in and out in seconds for convenience.

DETAILED DESCRIPTION

A sandal according to the present invention includes two molded plates which reciprocally and releasably lock together.

FIG. 14 #36 depicts the underside of the molded male plate which contains a rear snap protrusion #38, a center lock protrusion #39 which contains a forward vertical projection #40, and a frontal projection lock #41 a. which contains a vertical projection lock #41. The superior aspect of the male plate is the contact support for the foot #52, sometimes known as the insole. #37 is an empty space.

FIG. 15 depicts the molded female plate #43 whose superior aspect contains the Reciprocal releasable locking devices for the male plate. The rear socket #47, middle socket #46, and frontal socket #45, connect with the corresponding located locks of the male plate when joined together. #44 is a frontal ledge.

To insert the male plate into the female it is necessary to first insert the front lock #41 into the space #45 (of the female plate) by tilting the front of the male plate and first inserting the frontal lock #41 a. and #41 and the middle lock #39 And #40 into the corresponding front and middle sockets of the female plate #45 & 46. After entering the open sockets the male plate is eased forward until it meets resistance which means it is locked into place under the front ledge #44, and middle ledge of the female plate #47 a which will prevent it from lifting upward, and then the rear male lock #38 is pressed downward and snapped into the rear socket of the female plate #47

FIG. 16 depicts the male and female plates locked together #48. #51 is an open space through which the ankle strap is threaded

FIG. 17—depicts the underside of the male plate with choice of hook and loop fastener applied to its front and rear underside #57. An underside view of the male plate depicts the rear snap #54, middle lock #55 and frontal lock #56.

FIG. 18—depicts the female plate #58 inserted within the perimeter wall #63 of the superior base #59, the rear female lock socket #60, mid female lock socket #61, and front female lock socket #62.

FIG. 19 depicts the underside area of the male plate where the fastening material example of multiple tiny snap protrusions #64 are molded onto the underside front and rear area of the plate. #65 is a horizontal view of a snap protrusion

FIG. 20 depicts two choices of reciprocal releasable fastening materials attached to various underside areas of the straps being the female snap inlets #65 and hook and loop fastener #68, and one permanent fastener being glue #68 which is covered by a peel away tab #69 until ready for application.

FIG. 21 depicts tips of straps #67 in contact and secured with a choice of reciprocal fastener on the underside of the male plate, and an ankle strap #67 threaded through the rear snap outlet of the rear male snap crosses the heel horizontally
